I will read (listen to) books more directed to kids from time to time just to give myself a break from some of the more serious topics, and this is a great listen if you might do the same, or just enjoy a well written series without wanting to listen to something too long..

Right now, the 39 Clues books seem to be my go to when I'm taking one of my breaks..

They are well written, well narrated, and are overall great books for kids or adults. Think of an Indiana Jones adventure from a kids point of view.. Well rounded characters, plot twists that aren't too obvious, etc..

Overall, I would definitely recommend this book (and this series) if you aren't looking for something good and an ongoing story you can follow from time to time.. This is book 2 but I think I'm up to #5 now & have enjoyed every one so far (even bought the next because I was wanting to hear the next step in the adventure)... It will probably take me a few years before I get up to the last book, but I'm in no hurry..

My family -- son 8YO, daughter 10YO, my husband and I -- all LOVE listening to these books. The narrator is amazing. The story line is interesting and fast-paced and educational for everyone. The characters are entertaining. All in all, a great listen. I HIGHLY recommend this series to families for road trips or simply driving around town. It's amazing how much less bickering there is between my kids get in or how quickly a bad mood gets turned around once this book is turned on.

We had the first book in hard copy and read it together as a family. We couldn't wait for the library or purchase delivery. Unanimous that all wanted the audio book so we could just dream the story in our heads together. The clarity of the voices, the just right sound effects (not too much or too little) and just the suspense of the story is great! Definitely five stars in our family. We are going to continue alternating reading out loud and listening.

I love the 39 clues series and I love this 📚 I could listen to it day after day etc. Best 📚 I highly recommend this 📚 to anyone who likes a good cliffhanger or to someone who likes a great mystery.👍😊☺️

i cannot comment on every writer individually because the books sort of ran together for me during a week trip. I read them all and cannot pinpoint every writer.
I can say that they were all wonderful and have great stories mixed with history and geography. They can teach in a great fun exciting atmosphere.
